I've just finished reading the Kindle version of this book. It offers very good insights into Oldfield's music and his well-publicised psychological problems. It was interesting to learn that Richard Branson only allowed Oldfield one single week in the Manor studio to record side one of Tubular Bells - there clearly wasn't a lot of belief in Oldfield's musical vision at the time.
Mike Oldfield gives a lot of detail about the music and recording processes. However, he is very vague when he refers to his relationships with others, especially women, who - apart from his mother - barely get a mention in the book.
Despite his success and the admiration many have for his music, Mike Oldfield comes across as a rather sad and lonely figure, weighed down by his anxieties and social ineptness. Not the most uplifting read in the world, but if you are interested in his music, then you should read this book.
